With 2.6.33-rc3-git3 I now see 2 CPU's every on a normal boot, but its
locking up solid at this part of the boot process as usual.
ACPI: PCI Interrupt Link [AAZA] enabled at IRQ 22
HDA Intel 0000:00:0e.1: PCI INT B -> Link[AAZA] -> GSI 22 (level, low)
-> IRQ 22.
With acpi=noirq (2 CPU's)
================
kvm: Nested Virtualization enabled.
IT8716 Super IO detected
Parport_PC 00:0a: reported by plug and Play ACPI
Parport 0: PC-Style at 0x378, irq 7 [PCSPP, TRISTATE,EPP]
parport: irq 7 in use, resorting to polled operation
HDA Intel 0000:00:0e.1: PCI -> APIC IRQ transform: INT B -> IRQ 11

With acpi=ht (1 CPU)
=============
Hangs at:-
Loading drivees, configuring devices do_IRQ: 0.65 No irq handler for
vector (irq -1)

With acpi=off (2 CPU's)
========================
Hangs at same point as with acpi=noirq.

Thanks for the update.

[Sid Boyce]

Renaming this bug as the "only 1 CPU" bug has been fixed, but the hang
at HDA remains.
I shall plug in a SB Audigy and see if it will boot with that.
By disabling the on-board HDA Intel audio in the BIOS, the system boots.

With the PCI Audigy card in, the box wouldn't even enter POST, either
the Audigy is bad (unknown - from a box that couldn't see the drives) or
there is something faulty on the motherboard. I am currently running
2.6.33-rc4-git2 on the box with a Terratec Aureon 5.1 USB MK II sound card.

Sid.

The Audigy card is definitely bad as the original box now works fine
without it.
Something has definitely changed in the HDA Intel code or handling of it
that causes that card to cause a solid lock-up on kernels >2.6.32-git1.

I guess we should let Takashi know.

Thanks.

What I'd try first is to pass enable_msi=0 option.
The MSI is enabled as default on 2.6.33 kernel, and this might be
problematic on non-Intel mobo.

[Takashi Iwai]

At Mon, 25 Jan 2010 22:54:23 +0100,

Just to be sure -- it's an option for snd-hda-intel module.

[Sid Boyce]

I passed "modprobe snd-hda-intel enable_msi=0" on the kernel command
line, still locks up as before.

Sid.

OK, are you sure that the lock-up happens at snd-hda-intel module?
How about blacklist it once?

Takashi

[Takashi Iwai]

At Tue, 26 Jan 2010 07:40:03 +0100,

Oh, I overlooked this text. Of course, this can't work :)

"modprobe..." isn't for the kernel command line but for modprobe
configs, usually specified in /etc/modprobe.d/* file.

And... is this report for 2.6.32 or for 2.6.33?
If it's with 2.6.32, enable_msi=1 may help instead.

[Sid Boyce]

I had already tried that... it locks up at the same point also with
"enable_msi=1".
tindog:/etc/modprobe.d # less 50-sound.conf

options snd slots=snd-hda-intel,enable_msi=0
# mDsH.vLXC8EvZgR7:MCP55 High Definition Audio
alias snd-card-0 snd-hda-intel

The motherboard giving the problem is the Asus M2N32-SLI deluxe.
00:0e.1 Audio device: nVidia Corporation MCP55 High Definition Audio

No such problem with the Asus CROSSHAIR II FORMULA motherboard which
also has the

Is your adapter build as a module or is it compiled directly into the kernel?

This is the option for module snd, not snd-hda-intel.

options snd,enable_msi=0 slots=snd-hda-intel
# 9LTX.vLXC8EvZgR7:MCP55 High Definition Audio
alias snd-card-0 snd-hda-intel

enable_msi=0 or 1, it still hangs.

It's a line for module "snd,enable_msi=0", which is likely invalid :)

Takashi

[Rafael J. Wysocki]

options snd enable_msi=0 slots=snd-hda-intel

(ie. the comma shouldn't be present in there).

Heh, not quite right :)
You need just a new line containing:

options snd-hda-intel enable_msi=0

Takashi

[Sid Boyce]

Apologies, with the following it boots successfully.
options slots=snd-hda-intel

# 9LTX.vLXC8EvZgR7:MCP55 High Definition Audio
alias snd-card-0 snd-hda-intel

options snd-hda-intel enable_msi=0

Does that mean the problem is fixed in 2.6.33-rc5 or you still need the
enable_msi=0 workaround?

It boots only with the enable_msi=0 workaround.

OK, I added the corresponding quirk entry to sound git tree.
The patch will be included in the next pull request so that it'll
be fixed in 2.6.33-rc6.
